Technology Bigshot Chapter 521: : Launch into space]

Many things have become more free since Alphabet completed its "ice-breaking journey" and successfully returned to the Greater China market.

Just as "China Matrix cmsx" is about to conduct the first flight test of "Arc Eagle No. 1" aerospace transport aircraft, many pictures taken by the g satellite earlier were circulated on the Internet, and many news were given report. Especially in the past three days, there have been frequent movements on the runway of cmsx's space base, which cannot be concealed from the satellites in the sky.

And today, the latest pictures released by the g satellite show that a snow-white space transport aircraft appeared on the runway and the ant-like crowd around it even more indicates that cmsx has new actions today.

For this test flight, "China Matrix cmsx" did not issue any official announcement, but for a while, the aerospace and astronomical fields kept a focus on this matter, especially ESA, spaex, Amazon and NASA A large space agency or a space exploration company such as NASA.

Matrix Technology entered the field of space exploration with cmsx and was regarded as one of the most powerful competitors by all its peers.

"Last ten seconds countdown to launch, nine...eight...seven..."

The voice broadcast resounded in the working hall of the tower control center. Dozens of staff members performed their duties, staring at a series of data information, and everything was in order.

Ren Hong and Liu Yuliang stood side by side, both of them staring at the runway field at the window isolation opening without saying a word.

On the runway, the snow-white "Arc Eagle No. 1" has the outline of a huge Mitsubishi cone. The edges are smoothed, showing a striking streamlined body. The head shape is streamlined, with the largest end, and the edges and corners are relatively clear toward the back. The four huge engine jets at the rear are arranged in a tight "cross" shape, and the four jets are like a square rotated at a 45-degree angle.

"Arc Eagle No. 1" this time not only carried the "dual test flight" mission of the aircraft and the launch tower, but also carried a total mass of 41 tons of supply materials, which will be launched together. The 41 tons of supply goods will be It will be sent to the "Tianzhou" at an altitude of 478 kilometers.

Obviously, this is cmsx's full confidence in "Arc Eagle 1", which also gives great confidence to the two astronauts on board. The 41 tons of expensive supplies of up to 6.7 billion US dollars mean that this The first test flight is only allowed to succeed and not to fail. It can be said that confidence and pressure go hand in hand.

In the cockpit, the two astronauts were silent, swiping the buttons of the instruments in an orderly manner. After finishing everything quickly, one of the astronauts placed his right hand on the flank of his thigh. on the push valve handle.

At the same time, the four jet ports of the main propulsion engine at the end of the body were simultaneously reduced by one-third of the caliber.

"Three...two...one fire!!!"

The astronaut in the cockpit heard the sound, and without the slightest hesitation, pushed the push valve handle tightly held by the right hand forward, directly to the bottom, the co-pilot was concentrating on locking the data displayed by the instrument on the driver, sinking Sheng said: "The core engine has been activated, the propulsion power is steadily increasing, and the energy output ratio is normal..."

At that moment, the core energy supply system inside the "Arc Eagle No. 1" was activated, and the high energy storage "Purple Origin Crystal Stone" with a high amount of energy stored in it was frantically outputting high-purity energy through the energy matrix. This is then converted into the thrust of an aerospace transport aircraft.

The four jet ports at the end immediately sprayed four blue-white flames, and the tail flames three or four meters long were extremely gorgeous.

The bottom pulley of the aerospace transport aircraft is fixed to the three parallel ejection tracks. In fact, when the "Arc Eagle No. 1" was still on the ground, the main propulsion engine was still increasing the propulsion energy output power wildly. At this time, the ejection The orbit will carry more thrust than the main thrusters to provide acceleration to the space transporter.

On the runway field, at the moment of ignition, blue-white tail flames emerged from the four jet ports of the propulsion engine, and at the same time, the three juxtaposed ejection tracks that intersected with the body made a surging sound of the air valve. Instantly produces a volume of up to nearly 88 decibels, which can easily cause severe deafness in an adult.

The stationary "Arc Eagle No. 1" space transport aircraft was instantly pulled by the ejection track and "supported" towards the launch tower. The paths of the three ejection tracks were swept by the transport aircraft, leaving three straight lines. White fog, under the influence of the tail thruster, three segments of white fog then merged into one segment.

"Arc Eagle No. 1" has entered the curved ejection track of the launch tower from the ejection track on the horizontal runway. The sound of the sonic boom resounded suddenly, which means that the transport aircraft has exceeded the speed of sound.

Typically, professionally trained astronauts can withstand accelerations of up to 7 to 10 g, and "Arc Eagle 1" needs to complete the acceleration of 3 g from the start of takeoff to the ninth second, In addition, this process needs to complete a 90-degree inclination steering, from the horizontal to the relatively vertical altitude, which has huge requirements on the physical fitness of the astronauts.

The impact of acceleration on the body is experienced even by ordinary people in life. The most intuitive one is the lift of the elevator. During this period, it will be light-headed and heavy. The faster the acceleration, the more obvious it is, especially for the human body. As far as the blood circulation system is concerned, when the acceleration reaches a certain level, it will cause severe local congestion of human body functions, and severe ischemia in the other part. Mild effects will lead to inconvenient movements, and severe cases will make limbs stiff. The high risk level can even cause capillary damage and endanger life safety.

The acceleration of 3 g is not a problem for astronauts, but don't underestimate the acceleration of 3 g. Ordinary people will experience severe dizziness and nausea under the condition of acceleration of 3 g, and the acceleration of 5 g will cause severe dizziness and nausea. Serious damage to cerebral blood vessels and life-threatening consequences. Fortunately, for ordinary people, professional astronauts or pilots with excellent physical fitness and professional advanced **** suits can withstand greater acceleration.

It is worth mentioning that in today's aerospace activities, very few manned aircraft have accelerated more than 7 g as in the last century, and usually only maintain an acceleration of 3 to 5 g.

This is not to say that today's manned vehicles are not as good as before, but today's technology is more advanced. In the past, rocket boosters or manned vehicles had to reach a certain limit to safely send astronauts to space, but today's technology More advanced, more comprehensive facilities, and then let the astronauts suffer great pain will be counterproductive.

When the nose of "Fox Eagle No. 1" turns to the sky along the launch tower, the moment the body and the ejection track are separated at the top, the acceleration of two g has been completed, and then the acceleration of the ninth second will be When it reaches 3 g, it will finally accelerate to 3 g to maintain a stable speed and go to outer space.

The time between going back and forth between space and the ground, or between acceleration and deceleration, is the most painful time for astronauts, but fortunately, the pain lasts for a short time.
